问题     Man will never conquer space. Such a statement may sound ludicrous(荒唐的), after we have made such long 【S1】______ into space. Yet it expresses a truth that our forefathers knew and we have forgotten one that our descendants must learn again, in heartbreak and loneliness.
    Our age is in many ways unique, full of 【S2】______ that never occurred before and may never come again. They distort our thinking, making us believe that what is true now will be true forever, though perhaps on a large 【S3】______ . Because we have annihilated (消除) distance on this planet, we imagine that we can do the same in space. The truth is 【S4】______ , and we will see it more clearly if we forget the present and turn our minds toward the past.
    To our ancestors, the vastness of the earth was a(n) 【S5】______ factor in their thoughts and lives. No man could ever see more than a tiny 【S6】______ of the earth. Only a lifetime ago, parents waved farewell to their emigrating children, knowing they would never see them again.
    Now, within one 【S7】______ generation, all this has changed. Psychologically as well as physically, there are no longer any remote places on earth. When a friend leaves for what was once a distant country, he cannot feel the same sense of irrevocable(无法改变的) 【S8】______ that saddened our forefathers. We know that he is only hours away by jetliner, and we have merely to reach for the telephone to hear his voice.
    When the satellite communication network is fully established, it will be as easy to see friends on the far side of the earth as to talk to them on the other side of the town. Then the world will 【S9】______ no more. From a world that has become too small, we are moving out into one that will be forever too large, whose 【S10】______ will recede from us always more swiftly than we can reach out toward them.

A) frontiers       B) extensions          C) incredible           D) ambitious
E) shrink          F) isolate             G) dominant             H) strides
I) scale           J) exclusive           K) otherwise            L) fraction
M) diverse         N) separation          O) phenomena
【S10】
